A Ricardo can paint a set of kitchen cabinet in 6 hours. His father can do it in 4 hours. How long
will a take them if they work together?
PLSSS HELPP MEE
The time it will a take them for both ricardo and his father to finish the painting if they work together is;
t = 2.4 hours
Time for ricardo to paint the set of kitchen cabinets = 6 hours
Time for Ricardo's father to finish painting = 4 hours
This means that ricardo in 1 hour paints 1/6 of the cabinets
His father in 1 hour paints 1/4 of the cabinets
If they work together, in one hour, they would have painted;
1/6 + 1/4 = 5/12 of the cabinet
If 5/12 of the cabinet is done in an hour,then 12/12 will be done in; ((12/12) × 1)/(5/12)
⇒ 1 × 12/5
⇒ 2.4 hours

The correct answer is: " 2 hours and 24 minutes ";
or; write as: " 2.4 hours " .
____
Step-by-step explanation:
[tex]\frac{x}{4} + \frac{x}{6} = 1[/tex] ; → { " 1 (one) whole job." }.
We want to solve for "x" ; the total time, in "hours", that will take them if they work together.
What is the LCD (least common denominator of "4" and "6" ?
→ Note that "4 * 6 = 24" ; so, "24" would work, but let's see if we can find the LCD —a number less then "24" ;
4: 2, 4, 12, 16, 20, 24,
6: 1, 2, 3, 6, 12
⇒ We see that "12" is the LCD.
_____
So, " [tex]\frac{x}{4} = \frac{?}{12}[/tex] " ; to solve for "?" ;
→ 4 * (what value?) = 12 ?
→ 12 ÷ 4 = (that value) ; ⇒ = " 3 " .
_____
So: [tex]\frac{x}{4} = \frac{(x*3)}{(4*3)} = \frac{3x}{12}[/tex] ;
_____
Now: " [tex]\frac{x}{6} = \frac{?}{12}[/tex] " ; to solve for "?" ;
→ 6 * (what value?) = 12 ?
→ 12 ÷ 6 = (that value) ; ⇒ = " 2 " .
_____
So: " [tex]\frac{x}{6} = \frac{(x*2)}{(6*2)} = \frac{2x}{12}[/tex] ;
Now: → [tex]\frac{x}{4} + \frac{x}{6} = 1[/tex] ;
Substitute our converted values:
→ [tex]\frac{3x}{12} + \frac{2x}{12}=1[/tex] ;
Then simplify the "left-hand side" of the equation:
_____
→ [tex]\frac{3x}{12} + \frac{2x}{12} = \frac{(3x+2x)}{12}[/tex] = [tex]\frac{5x}{12}[/tex] ;
Now, rewrite the simplified equation; and bring down the "1" :
_____
→ [tex]\frac{5x}{12} = 1[/tex] ;
Now, solve for "x" ; as follows:
_____
⇒ 5x = ( 1 * 12 ) ;
→ 5x = 12 ;
Now, divide Each Side of the equation by "5" ;
to isolate "x" on one side of the equation; & to solve for "x" (in hours):
_____
→ 5x / 5 = 12 / 5 ;
_____
to get: x = (12/5) hours.
_____
Now: We have (12/5) of 1 hour ; 24/10
Note the exact conversion: " 60 min. = 1 hr." :
So, 12/5 of 60 minutes;
= " [tex]\frac{12}{5}[/tex] * [tex]}\frac{60}{1}[/tex] " (minutes) ;
____
The "5" cancels to a "1" ; and the "60" cancels to a "12" :
{since: "60 ÷ 5 = 12" ; & since: "5 ÷ 5 = 1 " .}.
→ And we can rewrite as:
" [tex]\frac{12}{1} * \frac{12}{1}[/tex] " (minutes) = "12 * 12" minutes = 144 minutes.
⇒ " 144 minutes" equals: How many hours? " 144 ÷ 60 = 2.4 hours " ;
or; more specifically:
⇒ We have "2 hours and _(some) minutes".
→ that is; " 2 hours plus 0.4 hour(s) " .
⇒ [tex]\frac{(0.4) hr}{1}*\frac{(60)min}{1 hr} = [(0.4)*(60)] minutes[/tex] ;
= 24 minutes.
____
Alternate method:
____
(12/5 hours) = (12 ÷ 5) hours = " 2.4 hours " ; (and continue if desired).
____
So: The correct answer is: " 2 hours and 24 minutes ";
or; write as: " 2.4 hours " .

The polynomial f(x) = x³-x²+px+q, where p and q are constants, has remainder 8 when divided by (x-1). If (x+1) is factor of f(x), find the values of p and q
Answer:p=-1 and q=1
Step-by-step explanation:
Answer:
p=3, q=5
Step-by-step explanation:
f(x) = x³-x²+px+q
factor: x+1 = 0 x = -1
(-1)³ - (-1)² + p*(-1) + q = 0
-2 - p + q = 0
p = q-2
(x-1) is factor of f(x) - 8, root x = 1 : f(x) = x³-x²+(q-2)x+q-8
(1)³ - (1)² + (q-2)(1) + q - 8 = 0
q - 2 + q - 8 = 0
2q = 10 q = 5
p = q-2 = 3
check: x³-x²+3x+5 = (x+1)(x²-2x+5)
x³-x²+3x+5 = (x²+3)(x-1) + 8

The U.S. population in 1910 was 92 million people. In 1990, the population was 280 million. This could model either a linear or exponential growth. You will create both and then look at the true population increase and decide which model is closer the the true growth.
Which list of number below represent the growth from 1910 to 1990 as an exponential model? (jumping every 20 years)
Question 3 options:
92 mil, 105 mil, 173 mil, 220 mil, 280 mil
92 mil, 110 mil, 175.5 mil, 220.8 mil, 280 mil
92 mil, 121.4 mil, 160.3 mil, 211.6 mil, 280 mil
92 mil, 139 mil, 186 mil, 233 mil, 280 mil
Answer:
this answer is simply exponential growth also you did not put in a graph so i have to kind of improvise here also this choice SHOULD be the answer: 92 mil, 139 mil, 186 mil, 233 mil, 280 mil

12x - 4=4(2x+1) What is x?
Answer:
x = 2
Step-by-step explanation:
12x - 4 = 4(2x + 1)
Distribution first
12x - 4 = 4(2x) + 4(1)
12x - 4 = 8x + 4
Isolate x to one side
12x - 4 - 8x = 8x - 8x + 4
12x - 8x - 4 = 4
4x - 4 = 4
4x - 4 + 4 = 4 + 4
4x = 8
4x/4 = 8/4
x = 2

If matrix A and B are inverses of each other,then A times B=I,where I is the identity matrix
We want to see if the given statement is true. (which is, by definition).
We define two inverse matrixes A and B as two matrixes that when multiplied are equal to a matrix with only ones in the diagonal.
This matrix with only ones in the diagonal (and zeros every else) is called the identity matrix.
Then the statement:
"If matrix A and B are inverses of each other, then A times B=I,where I is the identity matrix"
Is true by definition of inverse matrixes.

Answer:
20cm
Step-by-step explanation:
1. First find the area of the triangle
a = 1/2 × base × h
a = 1/2 × 10 × 11
a = 55cm²
2. Then times the area of the triangle by 8 to find the area of the rectangle
55 × 8 = 440cm²
3. Find the width of the rectangle:
The area of a rectangle is = l × w
22 × width = 440cm²
width = 440 ÷ 22
width = 20cm
Answer: Width = 20
Step-by-step explanation:
Give the area of triangle = x
So the area of rectangle = 8x
the area of triangle = (11 × 10) ÷ 2 = 55
So the area of rectangle = 8(55) = 440
The area of rectangle = W × L
So 440 = W × 22
W = 20

Answer:
Continuous graph:
- The height of a plant as it grows
- Amount of fuel and distance traveled.
Discrete graph:
- Number of students per teacher
- Amount of chairs for each table
Step-by-step explanation:
In mathematics "discrete" means specific points that do not possess a continuous line but only the plotting of points above certain integer values. On the other hand, the word "continuous" in mathematics would be a graph that has a constant smooth line that lacks jumps between values and sometimes decimal numbers.
"The number of students per teacher" would be discrete as the amount of students per teacher would be a fixed integer value.
"The height of a plant as it grows" would be continuous as the height of the plants increases the longer it grows. This would be represented by a straight continuous line.
"Amount of fuel and distance traveled" would be continuous as the amount of fuel used correlates with the distance traveled, which can be represented with a continuous line.
"Amount of chairs for each table" would be discrete as it would be a set integer value for the amount of chairs at each table, not a continuous line.

[tex]\frac{-2(|4x+12|)}{-2} = \frac{-32}{-2}[/tex] [tex]|4x + 12| = 16[/tex]Step 2: Solve absolute value.
We know either 4x + 12 = 16 or 4x + 12 = -16.1st Possibility:
